Electrical Parameters

Electrical Parameters

Electrical parameters are based on the following definition of conditions:

• On state (also referred to as the crowbar condition) is the low impedance condition

reached during full conduction and simulates a short circuit.

• Off state (also referred to as the blocking condition) is the high impedance condition prior

to beginning conduction and simulates an open circuit.

Off-state Capacitance — typical capacitance measured in off state

Rate of Rise of Current — maximum rated value of the acceptable rate of

rise in current over time

Rate of Rise of Voltage — rate of applied voltage over time

Switching Current — maximum current required to switch to on state

Leakage Current — maximum peak off-state current measured at VDRM

Holding Current — minimum current required to maintain on state

Peak Pulse Current — maximum rated peak impulse current

On-state Current — maximum rated continuous on-state current

Peak One-cycle Surge Current — maximum rated one-cycle AC current

Switching Voltage — maximum voltage prior to switching to on state

Peak Off-state Voltage — maximum voltage that can be applied while

maintaining off state

On-state Forward Voltage — maximum forward voltage measured at rated

on-state current

On-state Voltage — maximum voltage measured at rated on-state current
